Application filed July 31, 1905. Serial No. 272.084.

To a/ZZ whom it may concern,.- V

Be it known that I, VALERIUS D. ANDER- soN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Presses, of which the following is a specification.

My present invention pertains to improvements in presses, and relates more particularly to that class of machines which forms the basis of the following Letters Patent of the United States granted to me: No. 647,354, dated April 10, 1900, and Nos. 731,734, 731,735, and 731,737, dated June 23, 1903.

The object of the invention is primarily to provide an improved shell or casing the life of which is materially longer than that of the shell or casing shown in the patents re'- ferred to above.

The invention will be best understood upon reference to the accompanying'drawingFs, in whichigure 1 is a longitudinal vertical sectional view of the press or expeller; Fig. 2, a horizontal sectional view taken on the line 2 2 of Fig. 4; Fi 3, a perspective view of a portion of the she l or casing Fig. 4, an end elevation thereof, parts being broken away; Fig. 5, a detail sectional view on the line 5 5 of Fig. 3; Fig. 6, a similar view on the line 6 6 of Fig; 3; Fig. 7, an end elevation of a portion of the bars, parts being broken away and shown in section to more clearly illustrate the construction; Fig. 8, a detail side elevation of one of the spacing-rivets; Fig. 9, a perspective view of two of the bars; and'Fig. 10, an end elevation of three of the bars, showing a slightly-modified form of construction.

The main object of the invention is to provide a shell or casing with a series of openlngs therein of a predetermined width and to so construct the shell that the openings will rep main the same in size as they surface of the shell wears away through the action of the material thereon.

A further object of the invention is to provide a ready means for securing the bars of the shell in their adjusted positions.

A still further object is to provide means for properly spacing the bars and preventing the same from stacking.

Referring to the drawings, and more articularly to Fig. 1, A denotes the main riving-shaft of the press, upon which is mounted members, as

a screw section or quill B, which rotates with the shaft. A second screw-section C rotates about the forward end of the shaft,`said'shaft being driven from a gear D, while screw-section C 1s driven by a gear E. These screwsections carry Separated screws, as in my former patents, that serve to express the oil from the seed or other material which is fed to the press through a hopper F.

The material which is carried from the shell of the press (which will be hereinafter described in detail) is discharged through a casting or member G and over a conical disintegrating member H, the latter being adjustable toward and from the member G, as will be readily appreciated upon a mere inspection of Fig. 1.

The shell or casing is composedv of a series of bars extending longitudinally thereof, the

bars being carried by suitable supports hinged upon a shaft or rod l, Figs. 2 and 4, which extends longitudinally of the press and is mounted in suitable boxes or bearings formed in the main castings or frame of the press.- tudinally into an upper an lower section, one of which may be raised and thrown away from the screws, while the other may be droppedffor they samey pu ose. Both portions orsections of the shrill) construction, a description of one will suflice.

J J denote a series'of ribs or supporting members, made sufliciently heavy to withstand the enormous pressure which is exerted by the Screws in the disintegration andcom'- pression of the seeds or other material. These will be seen upon reference'to Figs. 1 and 2, are placed parallel to each other and hinged upon the rod l. Ad'acent to the discharge end of the press the ri s are brought closer together, inasmuch as the ressure exerted at this point is greater than at the forward or feed end of the press.

' The inner face of each rib is substantiall semicircular in form and is provided wit three notches, one being centrally disposed and adapted to receive a bar or member K, while the other notches are formed adjacent to the extremities of the rib anddesigned to receive the bars or rods L and M, the latter bein identical in form. Bar K is secured in therib bya ta -bolt N, (see Fig. 1,) while rods L and M are eld to the ribs by tap-bolts O, passing through lugs or ears P, extending Said shell or casin is divided longi,

being similar in'- outwardly from the ribs or members J. (See Figs. 3 and 5.) Each of the bars L and M is likewise provided with a mortise or groove upon its outer face, adapted to receive a tenon or ear Q of a shoe or wearing-face R, said shoe or wearing-face being secured by a series of bolts S, which pass through the shoe and the bar and securely hold the parts in position. The bolts prevent the ear from being withdrawn from the groove, and the groove holds the shoe against sidewise movement under the torsional action of the screw and the material forced around within and through the shell. The means shown for holding the shoein position permits the ready removal thereof when said member becomes worn through the action of the material passing through the press and also the substitution of a new shoe.

T denotes a wedge-sha ed member which is secured to the interme iate bar K by bolts U, passing through said bar or member VT and bar K, as best seen in Figs. 3, 6, and 7. A washer V, of a material which may be slightly compressed under heavy pressure, is introduced between the lower face of member T and the bar K, said member T acting, in conjunction with the fixed bars L and M, to properly position the intermediate bars and to firmly clamp them in their proper position.

The intermediate bars, as shown in Figs. 1, 2, 3, 4, 7, and 9, comprise a series of bars W, rectangular in cross-section, and a second series X, the inner edges of which latter are slightly beveled, the faces Y (see Figs. 7 and 9) standing in parallelism with the side faces of said rectangular bars W when the parts are assembled. It will, therefore, be seen that so long as the bars are properly spaced and held in exact ad'ustment the openings between the bars wili'remain the same until the bars wear down beyond the beveled faces Y.

It is essential tothe proper operation of a press of this character that the s aces between the bars be the same throng out and that the spaces should remain the same so long as the press is in operation. By providing each alternate bar with a beveled face, as just noted, the spacin will be constant for a long period, and the Tength of time during which the bar may be used is proportionately extended.

It is not material in the operation of the press that the separated screws should come into contact with the material, so that the screws and the inner face of the shell may wear away to a considerable extent, before the press becomes inoperative for the purpose of extracting oil or other liquid.

VIn order to properly space the bars, there is secured upon the opposite faces of each alternate bar a flat member A', preferably formed of a piece of clock-spring or like hard material, said members extending to the upper edge of the bar and being secured in position by a rivet B', which passes through said members and the bar. To prevent the bars from stacking under the action of the material in the press, the rivets are preferably formed as shown in detail in Figs. 7 and S-that is to say, they have a wedge-shaped head C and are formed with a similar head D upon the opposite end. Similar rivets B2 are passed through each of the bars W, the heads of said rivets abutting with the heads C D of the rivets in the bars X. It is conceivable, of course, that a Washer of the form shown may be employed instead of a long rivet having what ,may be termed a second head thereon. The bars being thus properly spaced at their inner edges and likewise held a fixed distance apart by the rivets, all stackin of the same is prevented. The bars W are likewise prevented from moving inward, as they mi ht otherwise do, were they not provided Wit bevel-headed rivets.

With the construction shownit is only necessary to loosen the wedge-shaped member T and insert the bars W and Xin alternation. Then by drawing said member T downwardly it acts upon the beveled faces of the immediately adjacent bars E', which, as is seen upon reference to Figs. 3 and 7, must'be of special form, thus serving to force the bars 95 against the rivet-heads and also against the ends of the spacing members A and against the fixed shoes R, whereby all the bars will be securely held in position and uniformly spaced throughout.

The outer ends of the bars W and X and also the bars or members K, L, and M are preferably supported upon a casting or frame F. (See Figs. 3, 4, 5, and 6.) Bar K is secured to said member by a bolt G.

Instead of beveling the face of each alternate bar it is conceivable that the outer faces of each bar may be beveled,as shown in Fig. 10. With this construction it is only necessary to employ the rivets B3 upon each alter- 1 1o nate bar, as the beveled faces reclude the inward movement of any of the ars.

New bars may be readily substituted when necessary. by simply loosening the wedgeshaped member T, which will permit the 1 15 ready Withdrawal of any or all of the bars. Another shoe may then be applied to eachof the bars L and M at the same time or when it becomes desirable to change the shoes for any reason. izo

inasmuch as the wear is greater in the final or discharge end of the press than in the forward end thereof, it is found desirable to vemploy two sets of bars in forming the shell'- that is to say, the bars do not extend throughr 25 out the length of the shell or are made in two sections, as is clearly indicated in Figs. 1, 2, and 3. It is conceivable that the bars may be made shorter, and in ractice I have employed a shell formed of our lengths of bars. 13o

IOO

Lof;

The shorter bars are easier to straighten and cost less to replace.

By providing the bars with beveled edges or faces close adjustment thereof at their in- 5 ner portions may be secured and at the same time a wide or divergent space is produced between the remaining portion of the adjacent bars, through which the liquid expressed from the matcr al undergoing treatment may freely pass. In other words, the graduallyincreasing space forms an opening which is not liable to become clogged.

Having thus described my invention, what I claim is 1. A shell for a press, comprising a substantially circular series of metallic bars, said bars being separately formed and secured together with their side faces in parallelism throughout those ortions which lie adjacent to the interior of t e shell.

2. A shell for a press, com rising a series of bars arranged side by side, t e adjacent faces of said bars at their inner portions standing parallel to each other while the remainder of 5 the space between each pair of bars gradually increases toward the outer faces of the bars. y

3. A shell for a press, comprising'a series of bars, said bars being substantially rectangular in cross-section and each alternate bar having those faces which are adjacent to the next bars slightly beveled so that said beveled ortions stand parallel to the next adjacent ars.

4. A shell for a press, com rising a series of radially-arranged bars, said ars being placed lside by side and having a space or opening of a definite width between the inner edges of each pair of bars, said space projecting inwardly between the bars to a limited extent while the bars are separated a greater distance throughout the remainder of their side faces, substantially as described.

5. A bar for the shell or casin of a press,

45 provided with inwardly-bevele side faces adjacent to its inner ed e.

6. vA bar for the shel or casing of a ress, said bar being substantially rectangu ar in cross-section and provided with inwardlybeveled faces extending throughout its length adjacent to the inner edge thereof.

7. A shell or casing for a press, comprising a series of bars the adjacent faces of said bars at their inner portions standing parallel to each other; a series of spacing members secured to the bars and adapted when the bars are assembled to separate the inner edges thereofy to a predetermined extent; and

means for preventing the bars from stacking 6o when the same are secured in position.

l 8. In combination with a supporting member having a curved face; a series of bars mounted thereon; means for spacing the bars i at their inner ed es; means independent of the spacing means or preventing the bars from stacking; and means for securing the bars in position upon said supfporting member.

9. A shellor casing or a press, comprising a series of supporting members havinglurved 'each of said members being provided with three notches or recesses, one of which is located at the mid-length of said rib while the others are formed adjacent to the outer faces of the rib; a bar mounted in each of said notches or recesses; a removable shoe secured to one face of each of the bars mounted in the outer recesses; a wedge-shaped member secured to the intermediate bar; and a series of loose bars resting upon the ribs intermmediate the wedge-shaped member and the outer bars, substantially as described.

11. In a press, the combination of a series of semicircular ribs or supporting members, each of said members being provided with three notches or recesses, one of which is located at the mid-length of said rib while the' others are formed adjacent to the outer faces of the rib; a bar mounted in each of said notches or recesses; a removable shoe secured to one face of each of the bars mounted in the outer recesses; a wedge-sha ed member secured to the intermediate' ar; a series of loose bars resting'upon the ribs intermediate the wedge-shaped member. and the outer bars; and means for securing the proper spacing of the bars as they are locked in position.

12. A bar for the shell of a press or the like, said bar having beveled faces adjacent to its inner edge, spacing members arranged upon the outer faces of the bar, and a rivet passing through said spacing members, the rivet being provided with a beveled head upon each end.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
